In NDPR, Hans Sluga reviews James Phillips's Heidegger's Volk: Between National Socialism and Poetry.

[I]n a 1952 essay on Georg Trakl Heidegger concerns himself with the term "Geschlecht" which in its manifold meanings relates once again also to the notion of Volk. The final lesson that Heidegger draws from this discussion, according to Phillips, is that "The Geschlecht, like the Volk, is missing, but only as such can it constitute human community."Dasein, Volk, and Geschlecht must therefore all be understood to belong to a metaphysics of absence which Phillips identifies at the heart of Heidegger's entire philosophical enterprise.
